24 alternatives to Little Rat – Chrome extension monitors network calls of all extensions

Hi HN I needed a way to monitor network calls made by chrome extensions so I made a small extension. You can install it by dropping the zip or crx into the extensions page. It'll be on the chrome store whenever/if it gets through the review. Hopefully it's useful to others. https://github.com/dnakov/little-rat https://twitter.com/dnak0v

Pigeon▲99
Hey HN, My friend and I built a Chrome extension called Pigeon because we kept Googling “Reddit + [product name]” whenever we wanted to know what real people thought about something. Pigeon saves that step by looking at what’s on the page, finding related Reddit discussions, and showing the most helpful comments and opinions in one place. We’ve both found it super useful when researching products or topics online and thought others might too. Check it out and let me know what you think!

I Created a Chrome Extension for PG: TRAB (Tweet Reporter and Blocker)▲42
A few days ago I saw this tweet from PG: https://twitter.com/paulg/status/1496549841912094733 ...and guessed it shouldn't be too hard to make a chrome extension to do this (I had never made a chrome extension before) So I took a stab at it - took me a bit over a day to make it, and it was fun to put together. I responded to his tweet with the link to the extension but I'm not sure if he would've seen it. edit: Looks like I missed the approval notification for the listing of this extension on the chrome store:…

FlowLens▲134
Hi HN, We often run into this with coding agents like Claude Code: debugging turns into copy-pasting logs, writing long explanations, and sharing screenshots. FlowLens is an MCP server plus a Chrome extension that captures browser context (video, console, network, user actions, storage) and makes it available to MCP-compatible agents like Claude Code. You can try it here: https://magentic.ai/flowlens Any feedback—good, bad, or brutal—is welcome.
